JOSEPH COCKFIELD, OF CLINTON, IOVA, ASSIGNOR TO MAX NATHAN, OF NEW YORK, N. Y.

LUBRICATOR.

SPECIFICATION forming part of Letters Patent N o. 461,382, dated October 13, 1891. Application led September 1, 1891. Serial No. 404,429. (No model.) v l I -To all whom it may concern.:

Be it known that I, JOSEPH COCKFIELD, a citizen of the United States, residing at Clinton, in the county of Clinton and State of Iowa, have invented a new and useful Improvement in Lubricators, of which the following is a specification.

The invention relates to that class of lubri cators (intended more particularly for use on locomotives) in which water, as a product of condensation of steam is caused to passgraduparticular object of the invention is to add to these two feeds a third one for the purpose of lubricating` the valves and cylinders of the air-brake pump of a locomotive-engine from the same oil-chamber, securing a device of increased eectiveness and convenience, combined with simplicity and repuced cost-of construction.

In the accompanying drawings I have represented a lubricator which embodies the several -features of my invention in their preferred form, and to thesedrawings I shall now refer in order to explain more clearly the nature of the invention and the manner in which the same is or may be carried into effect.

Figure l is a vertical central section of the lubricator on line l 1, Fig. 3. Fig. 2 is a like section on line 2 2, Fig'. 3. Fig. 3 is a horizontal section on line 3 3, Fig. l. Fig. 4 is a horizontal section on line 4 4, Fig. 2. Fig. 5 is a horizontal section on line 5 5, Fig. l. Fig. G is a vertical section on line 6 6, Fig. 3.

A is the oil-reservoir. B is the condenser sui-mounting said reservoir and communicating with the same by the passages C C2 C3, through which the water of condensation (as permitted by valve C) passes from the condenser to the lower part of the oil-reservoir.

D is a union-coupling on top of the condenser, to which is attached a pipe leading to the boiler and through which the condenser is supplied with steam from the boiler.

.Vithin the condenser are two independent pipes E and E', which extend up nearly to i the top of the condenser, and

purpose of effecting the feed I As a rule lubricators for' bracket.

at their upper ends are .provided with openings for the en-A trance of steam from the condenser.. Each pipe screws into the top of the oil-reservoir and there communicates with passages F and F. Passage F leads to the. upper sight-feed connection G and passage F to the upper sight-- feed' connection G. Each of these connections is like the other, so that a description of one will answer for both. Referring to these connections, (shown in section in Figs. l, 3, and 6,) they are provided with passages H and H, these latter leading to the oil-exit pipes H2, which again connect with the oilpipes (not shown) leading to the parts to be lubricated. They are also provided with screw-valves I, which control the openings K, through which the ascending oil passes from the sight-feed tubes on its way to pipes H2. The connection is also provided with a lateral extension-neck L, designed to receive 'a common stationary hand-oiler of well-known construction, consisting of a receptacle M and regulating-valve M. The neck L communicates by an independent passage N With'the oil-exit pipe H2. With each upper sight-feed connection G or G is combined a lower sightfeed connection O, having the usual feed-nozzle P and regulating-valve R.

S is the sight-feed tube intermediate between the two connections. At the bottom of the oil-receiver is the single cross-channel T, Which connects the two lower sight-feed connections, and into this lower end of the oil-feed pipe T', which leads from the upper part of the oil-chamber.

U is the tilling-plug,Vt-l1e drain-cock, and X the indicator, commonly employed to show the amount of oil in the oil-reservoir.

, 9 Y is a stud and nut by means of which the lubricator is secured to a suitable brace or In all the foregoing` particulars the lubricator is identical with the one for which Letters Patent of the United States N o. 357,931 were granted February 15, 1887.

To carry into effect the improvements which form tho subject of this invention, a third pipe ais placed within the condenser B. This pipe screws into the top of the oil-chamber, and there communicates with a passage b.

channel enters the IOC into or from these connections will be entirely and need no further description.

independent passage t' leading into oil-exit pipe f2, are also located on this upper connection e.

At the point K, where the upper connection G, with its passages H and c, joins the body part- Z with its passages F and b, I provide a steam-tight joint, so that the upper connections G and e will not communicate with each other, and all passages leading steam or oil distinct, separate, and independent.

The lower sight-feed connection I also provide with an extension-neck m to receive the lower sight-feed connection n, which again is provided with the feed-nozzle o and regulating-valve p.

R is the sight-feed tube intermediate be'- tween the connections e and fn.

The lower connection O is made with a branch passage s, which communicates with a similar passaget in the lower. connection n, so that it will be evident that the single oilpassage T will supply the oil to all lower connections.

The operation of the lubricator as herein described, the action and purpose of the pipes E E d in connection with passages F F b and contracted outlet -passages H and f', and also the operation of the stationary hand-oilers, are Well known to those skilled in the art I claim- 1 In a multiple-feed lubricator, the combination, with the oil-reservoir, condenser, internal equalizing steam-pipes, oil-pipe, waterpipe, regulating-valves,7 and auxiliary handoilers, of two upper sight-feed connections G and e, one being supported by the other and veach being provided with independent and internal steam-inlet passages from the condenser, and independent oil-outlet passages from the main reservoir and from the handoilers to the parts to be lubricated, substantially as and forA the purpose set forth.

2. In a multiple-feed lubricator, the combination, with the. oil-reservoir, condenser, in-A ternal equalizing steam-pipes, oil-pipe, waterpipe, regulating-valves7 and auxiliary handoilers,of an upper sight-feed connection G, provided with two independent steam-passages H and c to receive steam from the condenser, one of these passages c supplying the steam to a second upper connection e, which is supported by the irst one G, substantially as and for the purpose set forth.

3. In a multiple-feed lubricator, the combination of two lower sight-feed connections, one serving as support for the other and both being supplied with oilthrough a common channel T, with two upper sight-feed connections G and e, one being supported by the other and each provided with independent steam-inlet passages from the condenser and independent oil-outlet passages from the oilreservoir and from the hand-oiler to the parts to be lubricated, substantially as described.

In testimony whereof I have hereunto set my l1and,this 27th day of August, 1891, in' the presence of two subscribing witnesses.

JOSEPH COGKFIELD.
